Adult chimpanzees produce a unique vocal signal, the pant-grunt, when encountering higher-ranking group members. The behaviour is typically directed to a specific receiver and has thus been interpreted as a 'greeting' signal. The alpha male obtains a large share of these calls, followed by the other adult males of the group. In this study, we describe the development of pant-grunting behaviour from the first grunt-like calls of newborn babies to the fully developed pant-grunts in adults. Although babies produce grunts from very early on, they are not directed to others until about 2 months of age. Subsequently, socially directed grunting steadily increases in frequency to peak around 7 months of age, but then decreases again to reach a nadir in older infants and juveniles, while the specificity in use increases. During adolescence, grunt production increases again with grunts given most frequently to socially relevant individuals. As young chimpanzees are closely affiliated to their mothers for the first decade of their lives, we also compared the grunting patterns of mothers and their offspring, which revealed some influences in pant-grunt production. In conclusion, the acquisition of pant-grunting behaviour in chimpanzees is a long-lasting process with distinct developmental phases in which social influences by the mother and other group members are likely to play a role. 相似文献

Using a sample of 263 mother–child dyads, we examined the extent to which maternal emotional and cognitive support during a joint problem‐solving task when children were 3‐years‐old predicted children's academic skills 1 year later independent of each other, the quality of the home learning environment, and maternal emotional responsiveness. When all parenting measures were examined simultaneously, only maternal emotional support during problem solving and the quality of the home learning environment predicted unique variation in gains in pre‐academic skills from 3 to 4 years of age. The positive effect of emotional support during problem solving was especially apparent for children whose pre‐academic skills were low at the age of 3 years. These findings are discussed in light of the changing demands placed on young children and their parents as they prepare for entry to the formal school system.

In this investigation, we examined the validity of Levenson's Self-Report Psychopathy Scale (LSRP; Levenson, Kiehl, & Fitzpatrick, 1995) in a sample of undergraduate students (n = 403). Utilizing a step-down hierarchical multiple regression procedure (e.g., Arbisi, Ben-Porath, & McNulty, 2002), we used LSRP scores to predict psychopathic personality traits to determine the presence of gender-moderated test bias. Results indicate similar correlational magnitudes for men and women. However, systematic over- and underprediction of scores (i.e., differential intercepts) was found for external criteria measuring key affective (i.e., low empathy) and behavioral (i.e., aggression, antisocial behavior) components of the psychopathic personality, although these effects were generally small. 相似文献

Background
The aim of the present study was to compare psychological distress and substance use between migrant and non-migrant populations in a socially deprived area of Berlin.Methods
A population-based random sample stratified for age (18?C57?years) and gender (50% female) was retrieved from the registration office. A total of 143 persons were included in the study. The participation rate was 48.5% when contact was established. Psychological distress was assessed using the General Health Questionnaire (GHQ-28) with its four subscales, somatic symptoms, anxiety/insomnia, social dysfunction and severe depression. Substance use was quantified using the Alcohol Use Identification Disorder Test (AUDIT) and the Fagerstr?m Test for Nicotine Dependence (FTND).Results
Of the study population 51.3% were first or second generation migrants and lived more often in single households. Migrants had lower educational levels and lower employment rates. The mean scores of migrants and non-migrants did not differ on any of the subscales somatic symptoms, anxiety/depression, social dysfunction or severe depression of the GHQ-28. Non-migrants showed significantly higher risks regarding alcohol use.Discussion
The present study did not reveal any differences regarding symptom profiles in the spectrum of anxiety and depression between non-migrants and migrants who lived in a socially deprived area. Migrants may compensate higher social risk profiles with lower risks regarding alcohol use. Larger samples have to inform on possible differences regarding smoking and other substances. 相似文献276.

The positive impact of sleep on memory consolidation has been shown for human subjects in numerous studies, but there is still sparse knowledge on this topic in rats, one of the most prominent model species in neuroscience research. Here, we examined the role of sleep in the object-place recognition task, a task closely comparable to tasks typically applied for testing human declarative memory: It is a one-trial task, hippocampus-dependent, not stressful and can be repeated within the same animal. A test session consisted of the Sample trial, followed by a 2-h retention interval and a Test trial, the latter examining the memory the rat had for the places of two objects presented at the Sample trial. In Experiment 1, each rat was tested twice, with the retention interval taking place either in the morning or evening, i.e., in the inactive or active phase, respectively. Rats showed significantly (p<0.01) better memory for object place after the Morning session. To control for confounding circadian factors, in Experiment 2 rats were tested four times, i.e., in the morning or in the evening while sleep was or was not deprived. Sleep during the retention interval was recorded polysomnographically. Rats only showed significant memory for the target object place in the Test trial after the Morning retention interval in the absence of sleep deprivation, and recognition performance in this condition was significantly superior to that in the three other conditions (p<0.05). EEG recordings during spontaneous morning sleep revealed increased slow oscillation (0.85-2.0 Hz) and upper delta (2.0-4.0 Hz), but reduced spindle band (10.5-13.5 Hz) activity, as compared to evening sleep. However, spindle band power was increased in the Morning retention interval in comparison to a Morning Baseline period (p<0.05). We conclude that consolidation of object-place memory depends on sleep, and presumably requires NonREM sleep rich in both slow wave and spindle activity. 相似文献

Internalists about reasons generally insist that if a putative reason, R, is to count as a genuine normative reason for a particular agent to do something, then R must make a rational connection to some desire or interest of the agent in question. If internalism is true, but moral reasons purport to apply to agents independently of the particular desires, interests, and commitments they have, then we may be forced to conclude that moral reasons are incoherent. Richard Joyce (2001) develops an argument along these lines. Against this view, I argue that we can make sense of moral reasons as reasons that apply to, and are capable of motivating, agents independently of their prior interests and desires. More specifically, I argue that moral agents, in virtue of their capacities for empathy and shared intentionality, are sensitive to reasons that do not directly link up with their pre-existing ends. In particular, they are sensitive to, and hence can be motivated by, reasons grounded in the desires, projects, commitments, concerns, and interests of others. Moral reasons are a subset of this class of reasons to which moral agents are sensitive. Thus, moral agents can be motivated by moral reasons, even where such reasons fail to link up to their own pre-existing ends. 相似文献

Schizophrenia is very common in our society, yet many people, both clergy and lay, are afraid of it and do not know what to do when confronted with someone who suffers from the disorder. Strange ideas and behavior can be frightening for those who don't understand and often result in further marginalization, even within the church community. This article seeks to outline the main features of schizophrenia and considers how to deal with particular situations which may arise in pastoral care. It suggests ways of dealing with people who express religious delusions and also argues that the "staples" of pastoral care--relationship building, empathy and inclusion--may not always be appropriate in the care of people with schizophrenia, who often need a "safe distance" between themselves and others. Some practical advice for families is also offered. 相似文献
